Question

calculate the number of ions obtained from CaCl2 when 222 g of it dissolved in water​

Answer 1

ANSWER

1mole→111g of CaCl

2

∴222g of CaCl

2

is equivalent to 2 moles of CaCl

2

Since 1 formula unit CaCl

2

gives 3 ions, therefore, 1 mol of CaCl

2

will give 3moles of ions

2 moles of CaCl

2

would give 3×2=6 moles of ions.

No. of ions = No. of moles of ions X Avogadro number

=6×6.022×10

23

=36.132×10

23

=3.6132×10

24
